What is Calcium Citrate?

Calcium citrate is an advanced supplemental form of calcium. Calcium citrate is notable because it is easy to absorb and digest, exhibits high bioavailability, and is extremely well-tolerated in comparison to some other forms of calcium. Calcium carbonate, for example, may cause problems in those with gastrointestinal sensitivities. These issues seem more pronounced in adults over age 50, who have lower levels of stomach acid. The gastrointestinal distress and poor absorbability associated with some calcium supplements may be contributing factors to the widespread calcium deficiency among US adults.**

Since calcium citrate is a more acidic form, it is absorbed more comfortably and completely in those over age 50, even on an empty stomach. In addition, research has suggested that in some circumstances, calcium citrate may raise blood levels of calcium more effectively than other calcium varieties. For these reasons, it is considered an advanced form--with a slightly higher price point than more basic calcium forms.**

Calcium citrate provides all of the wellness benefits associated with calcium supplementation. It supports skeletal strength, healthy posture, and peak bone mineral density. Adequate calcium (including calcium citrate) and vitamin D as part of a healthy diet, along with regular exercise, may reduce the risk of osteoporosis later in life.**

In addition to its most famous role in promoting bone health, calcium helps to support health of the muscles, nervous system, colon and cardiovascular system. Calcium is also an especially important nutrient for women, particularly those who are pregnant, breastfeeding or in their senior years. Women in these groups require a significantly higher intake of calcium in order to maintain overall well-being.**

Calcium Citrate Supplements

Some calcium citrate supplements include vitamin D or vitamin D3 to help facilitate absorption. Magnesium, often as magnesium citrate, is another absorption-enhancing nutrient sometimes included in calcium citrate supplements. Calcium citrate supplements may be presented as tablets, capsules, liquids, or powders.**

Calcium Citrate Directions for Use

Before taking any nutritional supplement, be sure to speak with your health care provider. The Recommended Dietary Allowances for calcium are approximately 1,000 mg daily for men and 1,200 to 1,300 mg daily for women. As absorption of calcium citrate is most effective at dosage levels of 500 mg or less, it is advisable to spread out doses throughout the day. Calcium citrate capsules and tablets are commonly 200 mg or 250 mg.**
